Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the LVC logic family specifications align with the target system's voltage levels and drive requirements. Ensure the SOIC-20 footprint matches the printed circuit board design constraints. Check for any recent lifecycle status updates or alternative recommendations from the manufacturer.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is needed for low-voltage digital systems. The LVC series offers improved performance over standard LVC devices while maintaining compatibility. Consider the propagation delay characteristics relative to the system clock speed. Evaluate the thermal dissipation capabilities of the SOIC-20 package against the expected power consumption in the application environment.
